Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

In this study the hygienic quality of minced moose meat was examined with regard to the prevalence of different bacteria. The methods used are described in NMKL, "Nordic Method Committee for Food". The results show that the levels of Escherichia coli and coagulase positive staphylococci in the meat are too high. The reason for this might be environmental factors, such as high temperature and humidity during the time when the carcasses are hanging and when the meat is cut up..

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

Syftet med denna uppsats är att redogöra för varför tandhygienistyrket väljs och varför den två- eller treåriga utbildningen till tandhygienist söks? Uppsatsen ger en översikt hur tankegångarna tidigare har varit inför tandhygienist-utbildningens längd. Hösten 2010 ska den behörighetsutredning som regeringen tillsatt redovisa vad de kommit fram till om tandhygienistutbildningens längd. För att få svar på uppsatsens syfte har en enkät utlämnats till förstaårsstudenter på tandhygienistutbildningen i Kristianstad och Malmö. Resultaten från enkätundersökningen visar att endast hälften av tandhygieniststudenterna har utbildningen som sitt förstahandsval.

Denna rapport beskriver utvecklingsprocessen av en programvara som jag har skapat för ett företag inom livsmedelsindustrin. Detta företag har tillverkat en ny produktgren och krävde ett verktyg för administrering av allt från produktion till leveranser. Då den befintliga programvaran inte var lämpad för denna uppgift, utvecklades en skräddarsydd lösning för just detta ändamål och med hänsyn till företagets kompetens och utrustning. Den som läser denna rapport bör ha grundläggande förståelse för programutveckling samt programmeringsspråket C#..

Pica is a behavior that can be seen in several animal groups. In cats, it means that they are eating, chewing or licking on material that is non-food. In this study the data was collected through an online survey. In total 522 responses, of which 26% of the cats were exhibiting pica. It was found that 28% of the housecats and 26% of purebred cats exhibited pica.

Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.

In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.

Particular to the cat among our pets is its´ unique nutritional needs and metabolism. The cat cannot produce some nutrients by themselves and must get them through their diet. This means that the cat quickly can suffer from various diseases unless the nutritional needs are covered. In those cases where man is completely in control of the cat?s diet, the right knowledge is crucial for the cat?s wellbeing.

Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
